Trigger bodies can read <code>OLD</code> and <code>NEW<</code>, assign permitted <code>NEW</code> values, run conditional BEGIN/END bodies, and execute supported DML including <code>INSERT … SELECT</code>. Multiple triggers execute by registered priority. AFTER work may be configured as asynchronous, in which case its completion and failure are not identical to the originating statemen...")

• 13:02, 21 August 2026 Carli talk contribs created page Memory Management and Eviction (Created page with "MemCP tracks persisted shard columns, indexes, temporary columns, keytables, cache-engine objects, and string dictionaries in a global memory manager. The overall budget defaults to 50% of system RAM. A separate persisted-data budget defaults to 30%. Exact byte limits override percentages. If system available memory falls too low, MemCP can evict before its own configured budget is exhausted. Eviction is LRU-like and type-aware. Persistent shard eviction releases only...")

• 13:01, 21 August 2026 Carli talk contribs created page Transactions and Isolation (Created page with "Every SQL statement runs in an implicit transaction unless the session already has an explicit <code>BEGIN</code>/<code>COMMIT</code>/<code>ROLLBACK</code> transaction. The default cursor-stability mode applies writes directly with undo masks, gives statement atomicity, and rolls back on errors. MemCP also contains an ACID mode with snapshot visibility and optimistic commit conflict detection. Savepoints are used internally for nested trigger/error recovery. Transactio...") Tag: Visual edit
• 12:58, 21 August 2026 Carli talk contribs created page Query Planner and Physical Lowering (Created page with "MemCP compiles SQL into executable Scheme code. The planner first converts SQL into a logical representation, decorrelates subqueries, and chooses a join order. Only after those semantic decisions are complete does the physical lowerer select scans, indexes, caches, RecSets, computed columns, and other storage-engine operators. This separation is important: two queries that mean the same thing should reach the same logical representation even when they use different...") Tag: Visual edit
